Single coronary ostium in right coronary sinus: previously unreported "one for all" configuration

Area of Science:

• Cardiology
• Anatomical Variations
• Medical Imaging

Background:

• Coronary artery anomalies are rare and can present with diverse clinical symptoms.
• Atypical chest pain in a 63-year-old female prompted detailed cardiac investigation.

Observation:

• A single coronary ostium arising from the right coronary sinus of Valsalva was identified.
• The left anterior descending and left circumflex coronary arteries originated from separate right ventricular and right posterolateral branches, respectively.

Findings:

• A unique coronary artery configuration was observed where both major coronary arteries reconstituted retrogradely from the cardiac apex towards the base.
• This specific pattern of anomalous origin and retrograde reconstitution has not been previously reported in medical literature.

Implications:

• Highlights the importance of advanced imaging in diagnosing rare coronary artery anomalies.
• Suggests that even complex anatomical variations may be managed conservatively with favorable outcomes.
• Contributes to the understanding of coronary artery development and potential variations.
